Unity Async Strategy

Use this skill when the user is deciding how runtime work should be scheduled or cleaned up.

Decision Ladder

1. First ask whether the task needs per-frame work at all.
2. If not, prefer events, callbacks, or explicit method calls.
3. If a short Unity-bound sequence is needed, prefer coroutine.
4. Recommend UniTask only when:
   • the project already uses it, or
   • the user explicitly wants it and accepts the dependency.
5. Use Update only for true continuous simulation, polling, or input loops that cannot be event-driven.

Do not recommend UniTask just because it looks more advanced than coroutine.

Specific Guidance

• Avoid many unrelated Update methods if a more event-driven flow works.
• Cache references used in hot paths.
• Always define lifecycle ownership:
  • who starts the work
  • who cancels or stops it
  • when it is cleaned up
• In MonoBehaviour, prefer OnEnable / OnDisable / OnDestroy for subscribe-unsubscribe symmetry.
• Use IDisposable mainly for pure C# lifetimes, temporary subscriptions, or scope-based cleanup helpers, not as a cargo-cult replacement for Unity lifecycle methods.

Output Format

• Recommended scheduling model
• Why it fits
• Lifecycle / cancellation owner
• Hot-path risks
• Why the heavier alternative is unnecessary, if applicable
